Does someone know, what it could be.
After starting the engine the rpms are changing between 800 and 1800 (once a second or so)
If I restart asap. Everything is fine.

If I don’t restart asap the DSC and 4x4 lights come up and again a few seconds later the engine light.

The codereader doesn’t show any codes.

After waiting a few minutes and restart everything is fine.
This started two days ago and just tree times so far and just cold engine.

Today a second weird thing happened. If I’m in 6 gear (AT) at 1500, push 80% the engine stutters at around 2300. Stop pushing it works more or less keep on pushing limp mode starts. Restart the engine everything works except the stutter at high torque.

Kick down, everything works fine.

Thanks for your inputs and sorry for my english...(I hope it's understandable)

Another fuel pump going bad...?

Bring it into the dealer!

i think it might be a problem with X-drive cuz i had an E70 X5 in my bay with DSC and 4X4 light on it was doing other weird things too, but bring it back to the dealership and let them figure it out.

[So What]

HPFP!!!!!

HPFP wouldnt make the DSC or 4X4 light go on.

HPFP...bring it in for service and mention you think your HPFP just failed.

Yesterday
I testdrove quite a bit and im able to reproduce the limp mode. (every time)

Start at 5 or 6 gear at 1500 rpms full trottle (before kick down). if i stay on
the pedal with max boost at 2500 it comes first stutter and then limp.
If i lift the pedal as soon the stutter starts no limp.
After Limp and restart i can drive maybee once without stutter but after it comes.
This happens just in 5 and 6 gear.

now a second thing we know from 2.0...
if i "kick down" the limp mode comes when it changes from 4 to 5 gear at max rpm (7100 or so).

Today
Cheked cables/connections and those look fine to me. will check tomorrow with a MM.

Switched on the valet feature and it works fine after that. No Limp at all.

This shaking engine after start didnt show up since last time but its also a few degrees warmer in the morning.

By the way I'm spinning wheels on all 4 from first to second gear

Thanks for your inputs

Try setting all the TQ Curve values to 0% or bring back to stock and see if you get the stuttering and/or limp mode. If so, keep PROcede out and bring it to your SA, saying you think your HPFP just failed.

When you have tried gator's 0% settings and the HPFP is ok, you can try this ( v2.0.1 map ):

Thanks eugen
Thats what I will try sunday.
Why do you run those numbers. Did you have some issues or just to be on the save side? (which is also my point)

By the way what baud rate do you use with the SD100
I dont have a handshake till now (Paranis synchronised)

Thanks again

V2 is pretty new, I like to be on the save side. Had no issues with the predefined torque settings from Vishnu but others did, AFAIK @ redline. In addition I have an AT.

When you change the torque settings the ECU has to adopt again. Especially when you change from higher torque settings to lower ones, take your time before you rev up to redline under full load.

The posted settings work very well.

Today
I drove in "valet mode" and the first time using it code 2298 was there. not the half big engine, but the small one on top. 2298 was the code. did still apear after restart. cleared the code with the code reader.
does someone know what 2298 meands?
in the code page at vishnu is nothing written about 2298.

After that no more codes.

Thanks
Marcel
